When fancy-pants champagne purveyor Veuve Clicquot Ponsardin ordered up an arty vase from the London Institute of Contemporary Art, creator Oscar Diaz took a roundabout route toward showing off the French company’s signature yellow color of its booze bottles. Crafting three nested vases out of red, green and blue glass, the color combo results in some interesting hues, one of which resembles the shade of Veuve Clicquot’s fine champagne.
It's a clever demo of what happens when you combine primary colors. Sure, you could use all three vases separately, but we’d rather see the light shining through, showing us how just three colors can intertwine to make a Technicolor rainbow. Now we see the light: It’s what happens what you harmonize R, G, and B.
